Abstract To reduce the large measurement error caused by the weak nonlinear time-varying characteristics of sensitive materials during dynamic measurement, an identification method of dynamic sensitivity coefficient of force transducer is proposed. First, the kernel function matrix of the calibrated force transducer is obtained at different excitation frequencies; second, the singular value of kernel function matrix is modified by regularization method, and the identification model of dynamic sensitivity coefficient matrix is established. To verify the accuracy of the method, a sinusoidal force calibration device is used to calibrate the force transducer dynamically, and its dynamic sensitivity coefficient is identified. The experimental results show that the mean relative error of the identification method is 7.05%, and the standard deviation of arithmetic mean is 1.18, which are reduced by 65.86% and 88.00% compared with the traditional method. In all, this method can improve the dynamic performance of the calibrated force transducer.
